GENERAL INFORMATION

The FT400-Series ow computers are microcontroller-based

indicator/transmitters that display ow rate and total and

provide output signals. The FT415 is battery-powered and

provides a scalable pulse output. The FT420 is powered by

external DC voltage and has both pulse and 4-20 mA analog

outputs. When the FT420 is being used in the 4-20 mA mode,

it is a two-wire or loop-powered device, meaning that the

4-20 mA output signal doubles as its power supply.

The addition of a dual-relay output board (FT420 only) allows

for certain applications requiring contact output isolation (e.g.,

certain metering pumps and water treatment controls). Dual

solid state relays provide exactly the same pulse output as the

standard unit, and each can signal one external device. A non-

resettable total is also available. The FT420 can be ordered in

a plastic enclosure with a 115 Vac power supply for use with

mechanical meters, or with a built-in 115 Vac/12-24 Vdc dual

power supply for magmeters.

Both the FT415 and the FT420 can be factory-mounted on the

meter or remotely wall mounted with the brackets provided. The

FT420 is also available as a panel mount with an open back fo

easy installation in the users own electrical enclosure. Most

FT400s can be converted from wall-to-meter or meter-to-wal

mount congurations after installation if needed.

Housings for the wall and meter-mounted models are rugged

cast aluminum, potted and gasketed for maximum environ

mental protection. A membrane keypad allows settings to be

changed without removing the cover. (Password protection, a

standard feature on the FT420, can be used to prevent settings

from being changed.)
